As IT environments expand, they can become increasingly intricate, involving more accounts, VPCs, and the connections between them. AWS Transit Gateway is a solution designed to tackle such networking complexities by creating a hub-and-spoke model, which streamlines network routing and enhances security. With Transit Gateway, you can effectively link your Virtual Private Clouds (VPCs) across multiple accounts. For further insights into this topic, you can check out this blog post that delves deeper into automation solutions.
Conducting Route 53 health checks on private resources in a VPC using AWS Lambda and Amazon CloudWatch
If you’ve utilized Amazon Route 53 health checks to oversee your resources, you may have noticed that these checks require public IP addresses. This limitation exists because Route 53 health checkers are public entities, capable of monitoring only those hosts with publicly routable IPs. If you’re looking to monitor your private resources, there’s a comprehensive guide available at this link, which is an authority on the subject.
Transitioning from Transit VPC to AWS Transit Gateway
Amazon Virtual Private Cloud (Amazon VPC) enables you to create numerous virtual networks as needed, offering various options for interconnecting these networks with non-AWS infrastructures, such as on-premises data centers or remote offices. Most users begin their cloud journey with a handful of VPCs; however, as organizations scale, efficient management becomes crucial.
Debugging connectivity issues within Amazon VPC
AWS resources depend significantly on their network foundation to provide optimal service performance. For instance, while your databases may be meticulously optimized and your front-end application servers might be operating on top-tier Amazon EC2 instances, any underlying network issues can severely impact overall performance. Ensuring network stability is essential for maintaining service quality.
VPC sharing: A modern solution for managing multiple accounts and VPCs
My initial experience with AWS occurred shortly after the launch of the Asia Pacific (Sydney) AWS Region over six years ago. At that time, the AWS Management Console offered fewer services, and I quickly discovered the Amazon Virtual Private Cloud (VPC). In less than ten minutes, I was able to establish a new VPC with subnets and additional configurations, simplifying the management of multiple accounts.
Introducing Bring Your Own IP (BYOIP) for Amazon VPC
A public IP address plays a critical role in establishing your identity on the public internet. In situations like migration, whitelisting, or managing IP address reputation, maintaining your application’s existing IP address is vital. This feature ensures continuity during transitions, making it easier for application owners to manage their IP addresses effectively.
How to securely expose Internet applications at scale using Application Load Balancer and AWS PrivateLink
If you have applications distributed across various Virtual Private Clouds (VPCs) and are interested in making them accessible via the Internet, there are several strategies available. One method is to provide each VPC with its own dedicated Internet connectivity through an attached Internet gateway. Alternatively, you can centralize Internet access through an Application Load Balancer, which can streamline the process while enhancing security.
